Jaguar Land Rover are bringing back the '60s, with the decision to switch from their current V6 to an all-new straight-six in 2017. The current supercharged V6 is an ageing engine from the era of Ford ownership. Originally, the 3.8-litre straight-six featured on the legendary E-Type in the 1960s which was what made the company world famous. The new straight-six will be a part of Jaguar Land Rover's Ingenium engine family, which have an aluminium block and are developed in-house.
